Q

Jak funguje prijem potravy pres bunecna usta?

A

->Bunecna usta
->kolem potravy se vytvori obal z membrany potravni vakuola
->v ni se potrava rozlozi vstreba ziviny a zbytek vrhne ven

Nalevnici

Q

Jak funguje fagocytoza?

A

->Pomoci panozek
->Panozky obklopi potravu az bunka vse pohlti
->Vznikne potravni vakuola
->Co nepotrebuje vylouci

Q

Pohlavni proces

A

Spojovani dvou bunek (po splynuti se zygota hned deli)

Konjugace
-> vymena gen info pomoci bunecnych ust (nalevnici)
-> nerozdeleno na samci a samici, nevytvori se pohl bunky
-> kombinuje se gen info ale netvori se pohl bunky
